The Effect of Global Warming on Arctic Ecosystems

Redrawing the Arctic

Perhaps more than anywhere else on the planet, the effects of rising temperatures are obvious and observable in the Arctic. From sea-ice decline to shifting niches and threats to biodiversity, the future looks bleak at the north pole.

The Precautionary Principle

“The theory that an action should be taken when a problem or threat occurs, not after harm has been inflicted; an approach to decision- making in risk management which justifies preventive measures or policies despite scientific uncertainty about whether detrimental effects will occur“. From Dictionary.com.

So they key issue is this: we suspect that human activity leads to climate change. We are still collecting data to support (or refute) this hypothesis, and the evidence is growing stronger and stronger that anthropogenic climate destabilisation is true. In the meantime, should we wait for more evidence before taking action or should we take preventative and remedial measures now, in order to get a ‘head start’?
